ERW steel yeeb nkab, lossis Hluav Taws Xob Hluav Taws Xob Welded steel yeeb nkab, yog ib hom kev siv dav dav ntawm welded steel yeeb nkab hauv engineering field. Nws cov txheej txheem ntau lawm yog renowned rau siab continuity thiab automation, uas tsis tsuas yog ua kom lub stability ntawm vuam zoo tab sis kuj sib npaug ntau lawm efficiency thiab cov nqi tswj. Hauv qab no yog kev txhais lus ntawm tag nrho cov txheej txheem tsim khoom ntawmERW steel kavlos ntawm cov khoom siv raw mus rau cov khoom tiav, ua ke nrog cov khoom ua tiav tiav.
I. Raw Material Preparation and Pre-Cov txheej txheem kho
1. Raw Material Warehousing thiab tshuaj xyuas
ERW steel kav feem ntau siv kub- dov steel coils ua raw khoom. Tom qab cov hlau coils tuaj txog ntawm lub Hoobkas, kev tshuaj xyuas zoo li qub thiab kev kuaj xyuas kev ua tau zoo yog thawj zaug los xyuas kom meej tias cov tshuaj muaj pes tsawg leeg thiab cov khoom siv ntawm cov hlau ua tau raws li cov kev cai ntawm cov khoom sib xws. Tsuas yog cov ntaub ntawv tsim nyog tuaj yeem nkag mus rau hauv cov kab ntau lawm, uas yog thawj zaug dhau los ua kom cov kav hlau ua tiav.
2. Slitting
Raws li lub hom phiaj cov yeeb nkab sab nraud thiab phab ntsa thickness yuav tsum tau, tag nrho cov coil ntawm steel yog longitudinally slit rau hauv steel strips ntawm qhov dav dav. Slitting raug ncaj qha cuam tshuam rau kev tsim thiab vuam ruaj khov, ua rau nws yog ib qho tseem ceeb ntawm kev npaj hauv ERW ntau lawm.
II. Kev npaj tas mus li ua ntej tsim
3. Uncoiling thiab Butt Vuam
Tom qab cov hlau sawb yog uncoiled los ntawm ib tug uncoiler, qhov kawg ntawm txawv steel coils yog kev cob cog rua los ntawm lub taub qab vuam kom ua tiav tas mus li ntau lawm. Cov txheej txheem no tuaj yeem txo qis qis thiab ua kom ruaj khov ntawm cov kab ntau lawm.
4. Looping
Cov cuab yeej looping yog siv los khaws qee qhov ntev ntawm steel sawb, ua rau cov kab ntau lawm ua haujlwm txuas ntxiv thaum hloov cov hlau coils lossis cov cuab yeej ua haujlwm zoo -tuning. Cov txheej txheem no ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov kab kev ua haujlwm thiab kev ruaj ntseg ntawm vuam zoo.
III. Cov txheej txheem tseem ceeb ntawm cov yeeb nkab tsim thiab siab -Vuam zaus
5. Kev sib sau ua ke zoo
Tom qab nkag mus rau hauv lub tsev tsim, cov hlau sawb maj mam khoov mus rau hauv ib lub voj voos zoo li los ntawm ntau txoj kev yob hauv ib ntus. Cov txheej txheem zoo ua tiav qhov kev hloov kho ntawm cov yeeb nkab roundness thiab ntug kev sib raug zoo, tsim kom muaj txiaj ntsig zoo rau kev vuam tom ntej.
6. Extrusion thiab High -Vuam zaus
Nyob rau hauv qhov kev txiav txim siab ntawm - zaus tam sim no, cov npoo ntawm cov yeeb nkab yog rhuab mus rau lub xeev yas, thiab cov hlau ntawm ob sab yog extruded thiab fused los ntawm extrusion yob los ua ib tug tuab weld. Cov txheej txheem no tsis tas yuav tsum tau muab tub lim hlau, thiab cov vuam ua tiav los ntawm kev sib txuas ntawm cov hlau hauv lub hauv paus hlau nws tus kheej, uas yog lub hauv paus ntawm lub zog thiab ruaj khov ntawm ERW steel kav.
7. Kev tshem tawm sab hauv thiab sab nraud
Tom qab vuam, vuam burrs yuav raug tsim tawm sab hauv thiab sab nraum cov yeeb nkab. Tshem tawm cov burrs sab hauv thiab sab nraud los ntawm cov khoom siv tshwj xeeb tuaj yeem txhim kho qhov smoothness ntawm cov yeeb nkab phab ntsa, txo cov dej thauj mus los, thiab txhim kho cov tsos zoo.
IV. Weld Performance Stabilization Treatment
8. Induction Annealing
Lub weld cheeb tsam yog rhuab los ntawm nruab nrab zaus induction thiab txias maj mam, ua rau cov hlau qauv ntawm lub vuam cheeb tsam yuav zoo ib yam thiab tshem tawm welding residual kev nyuaj siab. Cov kauj ruam no yog qhov tseem ceeb heev rau kev txhim kho weld toughness thiab tag nrho cov kev pab cuam lub neej.
9. Cua txias thiab dej txias
Raws li cov txheej txheem yuav tsum tau ua, cov yeeb nkab steel tau dhau los ua cua txias lossis dej txias los tswj cov cua txias, ntxiv stabilizing cov cuab yeej ntawm cov vuam thiab cov hlau hauv qab, thiab tiv thaiv kev ua haujlwm hloov pauv los ntawm qhov tsis sib xws.
V. Dimensional Control thiab tiav cov txheej txheem ua tiav
10. Qhov loj me
Kev kho zaum kawg ntawm cov yeeb nkab txoj kab uas hla sab nraud yog ua los ntawm ib chav sizing kom paub meej tias qhov tseeb ntawm cov yeeb nkab steel tiav raws li cov qauv yuav tsum tau ua. ERW steel kav tuaj yeem ua tiav cov kab me me sab nraud ntawm cov theem no.
11. Ncaj nraim
Tag nrho cov yeeb nkab yog ncaj nraim los txhim kho qhov ncaj, muab cov kev mob zoo rau kev thauj mus los tom ntej, kev teeb tsa, thiab vuam.
12. Txiav ntev ntev
Raws li cov neeg siv khoom lossis cov qauv yuav tsum tau ua, cov yeeb nkab raug txiav rau hauv qhov ntev kom ntseeg tau tias lub ntsej muag tiaj tus thiab ntev ntev.
13. Dej ntws tawm sab hauv
Sab hauv phab ntsa ntawm cov yeeb nkab steel yog dej ntws nrog siab - cov dej siab kom tshem tawm cov khoom seem thiab txhim kho cov phab ntsa sab hauv kom huv, uas yog tshwj xeeb tshaj yog tsim rau cov dej xa mus.
VI. Kev tshuaj xyuas thiab kev tswj xyuas zoo
14. Ultrasonic Detection rau phaj
Kev tshuaj xyuas hauv online ultrasonic ntawm qhov vuam yog ua thaum lub sijhawm tsim khoom kom paub meej qhov tsis xws luag thiab xyuas kom tswj tau qhov vuam zoo.
15. Hydrostatic Test
Cov dej siab siab tshaj qhov ua haujlwm siab yog siv rau cov yeeb nkab steel los tshuaj xyuas nws lub siab - bearing peev thiab sealing kev ua tau zoo, uas yog ib qho tseem ceeb txuas los xyuas kom meej kev ruaj ntseg kev pab cuam.
16. Sib Nqus Particle Inspection thiab Residual Magnetism Test
Nto thiab ze ntawm - deg defects raug tshuaj xyuas los ntawm kev soj ntsuam cov khoom sib nqus, thiab cov khoom siv hlau nplaum seem yog ua kom tsis txhob muaj kev cuam tshuam ntawm cov hlau nplaum seem ntawm kev ua tom ntej lossis siv.
17. Qhov hnyav, ntsuas qhov ntev, thiab kev soj ntsuam zaum kawg
Txhua cov yeeb nkab steel yog ntsuas thiab ntsuas qhov ntev, thiab ua raws li kev txheeb xyuas ntawm cov tsos, qhov ntev, thiab cov cim, kom ntseeg tau tias txhua yam khoom xa tuaj ua raws li cov lus cog tseg thiab cov qauv siv tau.
VII. Kev kho deg thiab khaws cia
18. Tsis siv neeg Marking
Ib qho kev kos npe tsis siv neeg tau txais los kos cov ntaub ntawv xws li cov lus qhia tshwj xeeb, cov qauv, thiab cov lej kub ntawm cov yeeb nkab saum npoo kom yooj yim traceability thiab tswj.
19. Sab nrauv txheej
Raws li daim ntawv thov, cov yeeb nkab steel tuaj yeem raug tiv thaiv los tiv thaiv - xeb lossis tiv thaiv txheej txheej kho kom haum rau qhov chaw sib txawv.
20. Cia
Cov kav hlau uas tau dhau tag nrho cov txheej txheem tshuaj xyuas nkag mus rau hauv cov khoom tiav warehouse, npaj rau kev xa khoom.
Xaus
Los ntawm warehouseing steel coils mus rau kev xa cov khoom tiav, cov txheej txheem tsim khoom ntawm ERW steel kav yog qhov tsis tu ncua thiab zoo - qauv. Txhua tus txheej txheem tsom mus rau qhov tseeb qhov tseeb, vuam zoo, thiab kev nyab xeeb ntawm kev ua haujlwm. Nws yog qhov kev lag luam loj thiab ruaj khov uas ua rau ERW steel kav yuav tsum tau siv dav hauv kev tsim vaj tsev hauv nroog, kev xa hluav taws xob, kev tsim cov kav dej, thiab lwm yam.
Hais txog Huayang Steel Pipe
Tam sim no, Huayang Steel Pipe's ERW steel kav tuaj yeem tsim nrog ib txoj kab nruab nrab ntawm 73 txog 610 millimeters thiab tuaj yeem tsim tau raws li ntau yam kev cai. Cov khoom ua tau raws li ntau yam thoob ntiaj teb cov yeeb nkab pov thawj cov qauv, muab cov kev daws teeb meem ruaj khov thiab txhim khu kev qha rau cov haujlwm sib txawv engineering.
